Question:
I have a 800 watt pioneer amplifier hooked up to 2 12' kickerz. and was wondering where I would want my gain, and low pass filter set at for best sound. please help me.
Answers:
Well the BEST way to set gains is with an oscilloscope. Lacking that, the second best way is with a test CD, and a DMM.
I am going to assume you don't have an o-scope, so I will give you the procedure for setting it with a DMM. I will need to know what model the speakers are. Get back to me with that, and I will walk you through it.
Well since you have 2 speakers, I am going to assume they are ran parallel and both have a nominal 4 ohm rating. So the total ohms the amp will see is 2 ohms.
The formula we need is Voltage(V)= equals the square root of wattage(P)xResistance(R)
Or V=√800x2
=40
So now we know we need 40 Volts coming from our amp, into the 2 ohm load, to equal 800 watts(400 per speaker).
Now take a CD with a test tone at 50 or 60 Hz at 0db, and play it on repeat at 75/80% of your max volume on your deck. disconnect your subs, and take your DMM set it to read AC voltage, put it the +(red) to the + on the amp, and vice versa for the -(black). Now turn up your gains on your amp until it says 40 volts, and your golden.
Hope that was helpful, If you need any clarification, just ask.
I would set the LPF no higher than 100 Hz.
I have done this on MANY amps, never have I ran accross , or heard of one that could not handle the brief amount of time it takes(under 10 minutes) to set your gains.

The po' boy way to set your filter is to just put it at about 120 and then play something and listen closely to your subs while you make adjustments. All that matters is what you hear (and like). As for the gain....what I do is turn the gain all the way down, then get into the driver's seat and put in my most-listened-to music and then turn my high range speakers up to the highest point that I will be listening to them then I go back and slowly increase the gain until the subs are as loud as they can go without any distortion (flutter, broken sounding notes, etc.). If you do not like as much bass as a lot of us bassheads, then naturally you'd just leave it a little lower.
it really depends on what you like to listen to, who cares about all that other crap, its your system make it sound the way you feel more comfortable
You gotta be carefull with Ricky suggestion. Not ALL amps tolerate no load (having the subs unhooked and running).
